Retrospective Evaluation of Skin prick Tests to Various Allergens in Patients with Atopic Dermatitis

Abstract

Atopic   dermatitis    is  a   common   disease   affecting   many   people.   Avoidance   therapy   to   the aeroallergens   is a cost-effective  and safe measure to help atopic dermatitis  patients.  Skin prick test (SPT) is a well-established   method  to identify the responsible  allergens.

The aim of this study is to determine  most responsible  allergens that provoke  allergy in patients with atopic  dermatitis  in sallah Al-deen governorate.

A retrospective  study were conducted on 111 patients with atopic dermatitis, 65(59%)  of them were male  and 46(41%)  were female  . Age  of patients  was between  8 to 64 years with a mean of age: 32.56+ 9.82 yr.

These patients were referred  to allergic clinic of Tikrit  Teaching  Hospital, and skin prick test(SPT) response  to  allergens  was  done  which  shows  100(90%)  of the patients  had  positive  SPT,  (6%)of these patients  were  monosensitized   against  one  allergen  while  others  were  polysensitized   for more than  one allergen  in which (41%)  serisitized against  2 allergens  ,(36%)  sensitized  against 3 allergens and 7% were sensitized  against >4 allergenic  extracts.  In regard to frequencies  of main  allergen groups,  Pollens  (51%)  ' and Moulds(29%)   were  considered  the most  common  aeroallergens,  among  pollen  the bermuda  (34%) had the highest  rate of sensitization  while sensitization  to food allergens was(9%)  .

We concluded that pollens and in particular Bermuda were the frequent causative aeroallergens in patients with atopic dermatitis.
